ABSTRACT
Coal was a fossil fuel. The general sense was a combustible sedimentary rock,
formed from the deposition of organic matter, primarily the remains of plants and
were formed through the process of coalification. One of the coal deposits was in
Bangko Tengah Suban Jeriji, Muara Enim Regency, South Sumatra Province.
This research examines the design of the mine pit geometry by taking into account
safety and economic factors with probabilistic methods. The geometry of mining
that was used in this design include high levels of 18 meters and a width of berm
29 meters. The slope of the single slope 1:0.05 for overburden, interburden, and
underburden, 1:0,75 for seam D, and 1:1.00 for seam E. The oveall slope had a
depth of 200 meters with an angle of 27o for Highwall and 12o for Lowwall. The
Safety factor obtained in this design was 2,101 with PoF 0% for Highwall and
3,575 with PoF 0% for Lowwall. There were 4 inter-ramp on this design with
safety factor 1,260, 1,569, 3,495, and 3,455. All of inter-ramp had PoF 0%. The
value of the stripping ratio of this design obtained was 12,812.
Keywords : Single Slope, Overall slope, FK, PoF.
